Reversed-phase high-performance liquid chromatography is applied to studies of the chromatographic characteristics of calix[4]-, calix[6]-, and calix[8]arenes functionalized at the lower rim of the macrocycle by phosphoryl groups. Acetonitrile–water is used as the mobile phase, LiChrosorb 18 is the stationary phase, and ultraviolet detection is at 254 nm. The influence of the size and conformation of the calix[n]arene macrocyclic skeleton and the nature of substituents at the lower and upper rims on chromatographic characteristics of calix[n]arenes are determined. Retention times and capacity factors of calix[n]arenes are determined. It is found that the retention times of calix[n]arenes are determined mainly by the presence of hydrophobic tert-butyl groups at the upper rim of the macrocyclic ring.
